How can I fix my 2012 Jeep Wrangler JKU when the turn signal, horn and wipers stopped working. It doesn't seem to be a fuse as those elements are on separate fuses. This started happening when I drove up Pikes Peak but I don't know if the altitude can effect the electronics in that way.
I found at least one solution that seems to have worked. Unhook the battery, wait 10 minutes and then hook it back up. This forces a computer reset and magically everything started working again. When in doubt reboot!
